Application filed llecember 22, 1921. 7 Serial No. 524,125.

To all whom it may concern:

Be it known that 1-, WILLIAM J. ,Sno BAUER, .a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have made an invention appertaining to 'a'Gas'oline Purifier; and I do hereby declare the following to be a full,

.clear, and exact description of the invention,

such as will enable others-skilled in the art to which it appertains to make and use the same, reference being hadto the accompanying drawings and to the characters of reference marked thereon, which form a part of this specification.

My invention has for its object to provide a means for clarifying gasoline of materials that collect therein when used. for cloth. cleaning purposes. It particularly has for. its object to quickly remove dyes from gasoline. The invention provides a means for causing the. gasoline to come into intimate contact with a strong caustic solution which operates to precipitate or collect the dyes and other material that may be dissolved therein.

The invention may be contained in structures of difi'erent forms. practical application of the invention I have selected a structure containing the invention as an example of such structures and shall describe it hereinafter. The structure selected for purposes of illustration is Figure 1 of the drawings is a side broken view of the apparatus for clarifyin gasoline. Fig. 2 is a sectional view ta on on the line 2-2 indicated in Fig. 1.

1 in the figures is a container, preferably having a conical bottom 2. The container is supported by means of the frame 3. A pipe 4 extends into the container and is provided with a nozzle 5 having a plurality of openings 6. The nozzle 5 1s locatednear the lower end of the container and also in close proximity to the body. The opemngs 6 extend at an angle less than 90 to a plane extending through the axis of the nozzle 5 and the axis of the cone, so that a streamthat may be directed'throu h the openings 6 of the nozzle will strike is e inner surface of the cone-shaped bottom 2 of the container at an angle that will cause the stream to be directed along the inner surface of the cone and consequently around the axis of the cone.

The pipe 4 is connected with a suitable To illustrate a,

source of gasoline supply which has a considerable head-in order-to give some pressure to the gasoline contained in the pipe 4. If desired the head pressure may be produced by a suitable pump. The flow of the asolinemay be controlled by the valve 7 A nel or hopper 8 is connected to the container, whereby the container may be partlally filled with a strong caustic solution, such as lye formed by a solution of caustic soda or caustic potash. The container is partly filled with the caustic solution, preferably to about the point indicated in the drawings, namely, to a point above the nozzle 5. The connection between the funnel and the container may be controlled by suitable valves, such as the valve 9.

- When the gasoline is admitted through the pipe 4 after the desired amount of lye has been inserted in the container the gasolinewill pass with considerable pressure through the pipe land cause fine streams of gasoline to pass through the openings 6 and project the gasoline at an angle to the surface of the conical bottom of the container and thus cause a rapid whirling movement of the gasoline through the lye, which will bring the gasoline into intimate contact with the lye.

As the gasoline flows into the lye the level of the mixture of the lye and asoline rises within the container 1, while t e mixture is being whirled within the container.

A cone member 10 is supported within the container and preferably near the upper end of the cone-shaped bottom of the container.

. The lower edge of the cone 10 is disposed a short distance from the surface of the conical bottom 2 and so as to leave a comparatively wide opening at the edge of the cone 10 and between the cone 10 and the surface of the conical bottom 2. The cone 10 is also provided with a plurality of openings 11. It

, is supported by brackets 12 that extend to the bottom. When the mixture to a level above the cone10 the rapidity of its movements below the cone 10 continues but of the li uid below the cone 10 operating h 110 through e area of the space intermediate the lower edge of the cone 10 and the surface of the bottom of thescontamer 1, and

cated above the valve 18.

possibly also somewhat through the openings 11 formed in the cone 10. The lye andthe' precipitate that is formed is heavier than the gasoline and consequently while the mixture is being whirled they are thrown to the side of the container and when allowed to tend to pass out or settle from the portion of the mixture located above the cone 10. As the level of the mixture rises in the tank or container 1 and reaches near the topthe movement is reduced, so that the" gasoline may, if desired, be drawn off at the higher level or at intermediate vertical elevations or levels, while the gasoline is being whirled and thoroughly mixed with the lye below the cone 10. If desired, the tank may be filled to any desired level and then the supply of gasoline cut off and the lye and the precipitates allowed to settle at the bottom of the tank. This, of course, will produce a clearer gasoline. The gasoline may then be drawn oil at different levels through the pipes 13 and the flow may be controlled by the valves 14: that will direct the gasoline to the receptacle 15. The pipes 13 extend well into the tank to prevent the collection of dirt deposited on or maintained by the current at the inner'surfaces of the tank and the cone 10.

The receptacle 15 may be divided into two parts by means of the screen 16, whereby the precipitated material may be collected in one. part of the tank 15 and drawn oif through the pipe 17 that is controlled by the The gasoline clarified may be drawn off by the pipe 19, and the flow may be controlled by the valve 20. The precipitate and, any remaining lye maybe removed by means or the pipe 21 and the valve 22. The container may be cleaned by means of steam that is directed through the pipe 23. The outlet of the pipe 23 extends in a direction substantially tangential to the inner surface of thecone 10. This causes a whirl of steam and water that gradually forms and thus the wall of the tank and of the cone is washed by the whirling motion of the water and the precipitate is washed from the surface of the tank and is passed out through the pipe 21. I

If desired, a float 24: may be connected to a guided rod 25 to indicate the level of the liquid contained in the tank. A pipe 26 may be connected near the top of the container to prevent an overflow. The pipe 26-is connected to the receptacle 15.

I claim: In a gasoline purifier, a tank having inverted conical bottom portion, the cone c5 forming the bottom having considerable altitude relative to its base, a pipe extending downward along'the cone surface of the bottom portion of the tank to near the apex of the cone of the bottom of the tank, and having openings'extending at an angleto the vertical plane passing through the axis of the cone of the bottom of the tank and the axis of the pipe, the cone member having its apex locatedabove its base and the pe- 7&5 riphery of its base located near the base of the cone of the bottom portion of the tank and in spaced relation with respect to the cone of the bottom portion of the tank, the cone member having a plurality of openings, means for inserting a cleaning agent into the bottom portion of the tank, means for directing the material to be purified to the said pipe having the said openings, and means for drawing off the liquid at different levels.

In testimony whereof, I have hereunto signed 111 name to this specification.
